I have an original NC30 exhaust system on my NC35. It is very close to the swing arm. I was wondering if the bracket that is welded on the can needs to be secured on the bike?

As long as the exhaust is secure it doesn't matter so much about the bracket. The NC30 has two places the bracket bolts onto but most of the aftermarket systems only use one of them.

The exhausts do run quite close to the swinging arm though..

If you put some pictures up can tell you if it's too close.

Thanks for the reply.

I don't have any pictures, but the exhaust is actually touching the swinging arm. Someone fitted the system for me. I was wondering if I should try refitting it?
